Here's some stuff I purchased in mid-2012 from Brenda Huff, owner of Wisdom Tree. Note that I don't have the originals for any of these, all I received were digital copies:

Color Dreams promotional video
Video demonstrating Color Dreams products, and arguing that their games don't infringe on Nintendo's patents. Presumably this was sent to potential retailers. Has some footage of Baby Boomer and Raid 2020 with very slight differences from the final versions.

Unsorted Color Dreams scans
Color Dreams "history and tech" files, according to Brenda. There's a mix of 16 scans here, some of them from internal documents, others from contemporary publications reporting on the company. Some of the internal docs are duplicates of material that was posted on TRM's old Color Dreams site. I suggest taking a look at the archive of his page, as he has some related docs there that aren't in this collection.

Something I found noteworthy here was this document, which brainstorms games where "the NES would generate the backgrounds like they do now, but a new chip would generate the sprites" independent of the NES hardware. I'm assuming this is related to the "dual processor" cartridge that was proposed for Hellraiser.
